LAMP-WICK.

SPECIFICATIQN forming part of Letters Patent No. 470,113, dated March 1,1892.

Application iled March 23, 1891.

T0 all whom, it may concern: I

Be it known that I, MAXWELL EDWARDS ELDER, engineer, a subject of theQueen of Great Britain, resid ing at Mosley Villa, 3 Tuns Lane, Formby,in the county of Lancaster, in the Kingdom of England, have inventedcertain new and useful Improvements in Lamp- Wioks,of whichthefollowingis a specification.

This invention relates to improvements in wicks for mineral or other oilor spirit burning lamps; and the object of my improvement is to providesaid wicks with tips of peculiar construction, which shall beincombustible, or nearly so, and which shall not require to be oftentrimmed or cleaned.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawing, which is avertical section showing my invention applied to a fiat wick providedwith a iiat internal core.

The body of the wick consists of an outer piece A, which may be ofordinary woven material, and of an inner core a of similar stuff. Thecap or tip B of incombustible material is bifurcated at its lower part.The wing portions b, formed by the bifurcation, are so disposed thatthey lie between the outer piece A and the inner core a, so that whenthe wick is in use it is provided with a side feed of oil, in additionto the central feed, th rough the pores of the asbestus.

In the manufacture of this wick I prefer to 4allow the outer piece A tosurround the tip B Serial No. 386.081. (No model.)

to such a height as to be level with its upper edge, as shown in dottedlines. Vhen in use, this outer piece will burn down for a certaindistance. There is thus no possibility of the piece A stopping short ofthe base of the flame, and the advantage of the side feed can beutilized to the fullest extent. v

The tip B may be attached to the body of the wick by stitches orotherwise. The tip, being incombustible, or nearly so, seldom requirestrimming or cleaning, and as the flame does not come in contact Withthewick proper, (except at the extreme base,) the wick remains practicallyunburned and may be retipped when required.

I Wish it to be understood that the invention is not confined .to datwicks, but is applicable to all kinds of wicks, whether cylindrical,circular, oval, square, or other shape, and either spun, woven, orknitted.

I declare that what I claim is- The combination, with a lamp-Wick havingan internal absorbent core surrounded by an outer absorbent case, of atip of porous iueombustible material securely attached thereto andpartly inclosed between the core and outercase, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

MAXWELL EDWARDS ELDER.
